纵横向荷载作用下厚板问题的边界元分析

An Analysis of Thick Plates underIn-plane and Transversal Loadings by the BEM

根据纵、横向荷载作用下厚板问题的受力特点， 引入等效荷载的概念［１］ ， 以边界元法理论建立了该问题的边界元求解线性方程组。这为解决复杂荷戴作用下厚板问题，以及上部结构与基础及地基共同作用问题等提供了一种新的分析方法。

In accordance with the behaviours of thick plates under the in-plane and transversal loadings,and introducing the concept of equivalent load, the coupled equations for the problem have been deduced with the theory of BEM in this paper.Thus a new method is presented for solving the problems of interaction of superstructure and foundation and subsoil,as well as for the problems of the thick plates under the complicated loadings.
